A poster is on top of a building. A person is standing on the ground at a distance of 50 m from the building. The angles of elevation to the top of the poster and bottom of the poster are $$45^{\circ}$$ and $$30^{\circ}$$, respectively. What is 200% of the height (in m) of the poster?

A

$$\frac{25}{3}\left(3-\sqrt{3}\right)$$

B

$$\frac{75}{3}\left(3-\sqrt{3}\right)$$

C

$$\frac{50}{3}\left(3-\sqrt{3}\right)$$

D

$$\frac{100}{3}\left(3-\sqrt{3}\right)$$
